To (1J/Z whom it Hefty concern,.-

Be it known that l, PETER NovAK, a subject of the Emperor of Austria, residing at Elizabethport, in the county of Union and State of New Jersey, have invented certain new and useful Improvements in Combination-Tools; and l do hereby declare the fol- This invention has reference generally to i improvements in that class of tools which are designed for use as squares, bevels, or miters and marking-gages; and the invention relates more particularly to a novel combined rule and bevel provided with any adjustable marking-gage which is conveniently attached and is movably :arranged upon a graduated scale or rule.

The invention therefore has for its principal object to provide a novel and simply constructed combination-tool of the general character hereinafter more fully set forth, all with a view'of securing a quick and easy adjustment of the various parts, so as to be capable of use as a T-square, a try-square, a miter or bevel, yor as a marking-gage.

Other objects and advantages'of the present invention will be brought out and made clear in the following detailed description.

Vith the various objects of my present invention in view the same consists primarily in the novel combination-tool hereinafter more fully set forth; and, furthermore, this invention consists in the various Aarrangements and combinations of parts, as well as in 'the-details of the construction of the same, all of which will be hereinafter more fully described and then finally embodied in the clauses of the claim which are appended to and which form, an essential part of this specification.

The invention is clearly'illustrated in the accompanying drawings, in which- Figure 1 is a plan or top view of the combination-tool, showing the marking-gage set for marking and illustrating in connection therewith and in dotted outline the position of 'the marking-gage when the latter is not in use. Fie'. 2 is a similar view of the tool, showing 'the parts set at `an angle of fortyfive degrees when the tool is to be used as a miter. Fig. 3 is an end view ofthe tool, the par-ts being set as indicated in said Fig. 1; and Fig. 4 is a bottom view of the `tool with the straight-edge or rule of the tool represented as being broken away. Fig. 5 is a transverse sectional representation in detail and on a slightly-enlarged scale, said section being taken on line 5 5 in said Fig. 4 looking in the direction of the arrow as; and Fig. 6 is a horizontal det-ail sectional representation, said section being taken on line 6 6 in said Fig. 5 looking in the direction of the arrow y. Fig. 7 is a plan or top view of the tool, showing the two slidably-connected sections or members of the straight-edge or rule drawn out tok their full extent, with the markinggage set at or near the eXtreme end portion of the straight-edge or rule; and Fig. 8 is a view of the parts shown in said Fig. 7, the tool being represented partly in side elevation and partly in longitudinal vertical section. Fig. 9 is a longitudinal vertical section of the tool, said section being taken on line 9 9 in said Fig. 1. Fig. 10 is a transverse vertical section taken on line 10 10 in said Fig. 1 looking in the direction of the arrow z, and Fig. 11 is a similar section taken on line 11 11 in said Fig. 1 with the markinggage in its normal initial position when not in use. Fig. 12 is a longitudinal vertical section of the tool similar to that shown in Fig.

49 with the marking-gage shown in its releasing relation with a latch -or lock device for permitting the extension of the members of the straight-edge or rule of the tool. Fig. 13 is a transverse section taken on line 13 13 in said Fig. 9, and Fig. 14 is a similar section taken on line 14 14 in the same figure. Fig. 15 is an end view, and Fig. 16 is a top view, of the marking device detached from the tool.

Similar characters of reference are employed in all of the above-described viewsv to indicate corresponding parts.

Referring now to the said several figures of the drawings, the reference character 1 indicates the complete tool, the same comprising an end member or stock 2, preferably of a segmental or semicircular coniiguration, the said member or stock being provided with a straight-edge 3, which is usually formed with a rib 4 and having a semicircular slot or opening 5. The member or stock 2 is also provided with a pivotal post 6 near the edge 3, said post being usually a screw formed with a head 7 and provided upon its lower screw-threaded por- IOO IlO

l is a straight-edge or rule, the same consisting circular opening or slot5.

of two slidably-connected members or elements 12 and 13 each of which is provided with suitable graduations 14 in inches or otherwise. As shown, the member or element 13 is made to swing upon the post 6, the head 7 of the latter being preferably covuntersunk in the upper surface of the member or element 12, substantially as shown. The end portion 15 of said member or element, which is movably disposed upon the upper surface of the member or stock 2, is provided in its under portion with a longitudinally-extending channel 16, forming va suitable guide or box, and with an elongated opening 17, as clearly shown. A block 18 is movably arranged in said channel 16, said block being provided with a downwardlyextending stud orpost 19, preferably of an .angular or squarev cross-section, said stud or post projecting into and through the semi- The end of said stud or post 19 which projects from said Aopening 5 is provided with a screw-thread 20, upon which is screwed a suitable nut 21, said nut being arranged in the recessed part 22, formed inthe lower surface of the member or stock 2, substantially as illustrated. Upon its upper surface the said block 18 is Vprovided with a screw-threaded post or stud 23, which projects into and above the elongated opening 17, as shown, and is provided with a suitable tightening-nut or thumbscrew 24, all arranged for tightening the member or element 12 in any one of its adjusted relations upon said member or stock 2, as will be clearly evident from an inspec- .tion of the several figures of the drawings.

The previously-mentioned recesses or receiving portions 11 are for the purpose of sliding the squared or Aangular portion of the stud or post 19 into any one of said recesses 11 when the nut or thumbscrew 24 is slightly loosened, whereby the member or element 12 can be secured at right angles or at fortyiive degrees to the straight-edge 3 of the stock 2, as will be clearly understood. Thus while it is advantageous to have the recesses 11y for readily and exactly adjusting the member or element 12 in its right-angled or forty-five degree relation to the edge 3 it will also be clearly understood that any other angular relation of the element or curing or tightening the parts in any other positions intermediate of any two of said recesses 11 or between the end recesses and the end portions 25 of the semicircular opening or slot 5 of the member or stock 2'.

Referring now more particularly to Figs. 7, 8, 10, and 11 of the drawings, it willv be seen that that portion of the rule member or element 12 which is movably arranged upon the member or stock 2 is made with a cen trally-disposed and longitudinally-extending raised portion 26, forlned with the undercut marginal edges 27. At a suitable point, asy at 23, the remaining portion of said member or element 12 is reduced in thickness, said reduced portion being provided with a cen trally-disposed and longitudinally-extending raised portion or rib 29, formed with the undercut marginal edges 30, substantially as shown in lugs. 13 and 14 of the drawings. One of the marginal edge portions of said reduced portion, as will be seen from Fig. 7, is r also provided with scale graduations 31 in inches or otherwise.v At a suitablev oint the said reduced portionv is also `provide with an upwardly-extending stud or projection .32,

which may be a screw, as here shown, and with a receiving depression or socket 33. The previously-mentioned rule member or element 13, as will be seen from the drawings, is made with a centrally-disposed and longitudinally-extending raised portion or rib 34, formed with the undercut marginal edges 35. Upon its under face the'said member or element 13is made with a longitudinally-extending depression or channel 36., formed by the marginal edge portions 37, the parts 'being made to dovetail over the raised portion or rib 29 of the reduced portion of the member or element 12, so that the element 13 is slidably arranged upon said reduced.. portion of the element 12, as will be clearly understood. To limit this slidingmovement and to prevent the separation or pulling apart of the two elements 12 and 13, a longitudinally-extending groove or channel 38 is formed -in the bottom of the member 13, into which the stud or projection 32 of the member 12 extends, as shown in Figs. 8, 12, and 13 of the drawings, and operates in a manner which will be fully understood from an inspection of the -figures of the drawings. The said member or element 13 is also preferably provided with a slot 39, across which extends a pin 40 and upon which is fulcrumed, so as -member to said edge 3 may be had by sethe member or element 13, substantially as IOS shown in Fig. 9 of the drawings, and the two rule members or elements 12 and 13 are held against any mo vement until the nosing 42 of .the lever 41 is withdrawn from the socket 33 by means of the scratch-gage in the manner to be presently described.

The scratch-gage consists, essentially, of a suita bly-formed body 44, formed in its under 'face with a channel or depression 45 and the .adjusted positions, a suitable set-screw 47,

provided with a suitable 'linger-piece 48, is provided, the operation of which will be clearly evident from the drawings. The said body 44 is also made with a laterally-extending arm or member 49, formed with a downwardly-extending portion 50. ln a screwthreaded hole 51 of said arm 49 and its por- -tion 50 is a screw-threaded shank 52, provided with a suitable iinger-piece 53 for screwing said shank down and bringing a scratch-point 54 on said shank below the lower surface' of the portion 5() after the body has been moved into any one of its adjusted positions and secured in such position for the purposes of marking or scratching. The body 44 is made with the edge 55 for setting the gage to any one of the graduations with which the rule members or elements are provided. When it is desired to draw out or extend the two members or elements 12 and 13, all that is then necessary is to slip the scratch-gage over the projecting vend portion of the lever 41., substantially as indicated in Fig. 1.2 of the drawings, whereby the nosing 42 is withdrawn from the socket 33, and the parts can be drawn out or eX-- tended. VVhen extended in thisA manner, the scratch-gage may be moved into any other position upon said member or element and secured in its adjusted position by means 'of the binding or set screw previously mentioned.

To produce a slight binding or holding relation between the two rule members or elements 1.2 and 13 when they are drawn ou and to overcome any loose ht, which might render the device useless and inoperative, a verythin and slightly-bowed spring-plate 56 may be secured upon one of the undercut marginal edges of the reduced part of the member or element 12, substantially in the manner illustrated in Fig. 7 or the drawings, the bowed part of said spring being in frictional binding relation or engagement with the inner surface of one of the downwardlyprojecting portions which provide the channel 38 ol the element or member 13, as will be clearly understood from an inspection ol said Fig. 7.

lirom the foregoing description of the present invention it will be 'clearly evident that a very simple and easily-manipulated tool has been produced and one which may be used for various purposes.

The adjustable feature of the two-rule elements or members 12 and 13 also has this advantage that the tool can be shortened to at least one-half its length for use on small work or when it is to be stored away in the tool-chest, so as to take up but very .little room.
